feat(app-server): update remote control APIs for better UX (#22877)

## Why
To help improve `codex remote-control` CLI UX which I plan to do in a
followup, this PR adds `server-name` to the various remote control APIs:
- `remoteControl/enable`
- `remoteControl/disable`
- `remoteControl/status/changed`

Also, add a `remoteControl/status/read` API. This will be helpful in the
Codex App.
